摘要
An improved lightweight z-axis (vertical) drilling apparatus for a commercial PCB drilling systems that uses a pair of unitary z-axis movement guides that integrate the vertical, guided movement of the linear actuator, spindle and pressure foot of a PCB drilling apparatus. The linear actuator is positioned directly above and coupled to the spindle, and the unitary z-axis movement guides situated such that the such that the center of mass of all of the drilling assembly's moving components is collinear with the axis of rotation of the motor and spindle. The combination of these improvements allows for faster drilling times, shorter drilling cycles, less drill bit wander, slower drill bit dulling and less drill bit breakage.
